Composite Race Car Bodies

You Never Forget Your First One My first car was a greenish-brown 1969 Buick LeSabre with a 123-inch wheel base and a 230-horsepower two-barrel V-8. That puppy weighed about 4200 lbs and taught me everything […]

The Kansas Monozone Tire

OK, so ‘monozone’ is just a fancy way of saying it’s the old tire.  It’s all in the branding, isn’t it? Goodyear has been experimenting with multi-zone tires since last year.  Multizone tires attempt to […]

Is More Data Always Better?

Saturday’s race in Richmond was a festival of miscues. Carl Edwards mistakenly thought he was leading, then he jumped the restart, although he wasn’t the one to lead the restart because he wasn’t the leader.
